Abstract: An optically detectable marker having a matrix material, which is doped with individual luminescent dopants, including a first luminescent dopant and a second luminescent dopant. The first luminescent dopant includes a first unique absorption band such that the first dopant may be excited by illumination of a first wavelength. The first dopant is distributed in the matrix material so as to form a first spatial pattern in the matrix material, which pattern may be optically detected by illuminating the marker by a light source illuminating light of the first wavelength. The second luminescent dopant includes a second unique absorption band such that the second dopant may be excited by illumination of a second wavelength, different from the first. The second dopant is distributed in the matrix material so as to form a second spatial pattern in the matrix material, which pattern may be optically detected by illuminating the marker by a light source illuminating light of the second wavelength.

Abstract: The present invention relates to a new class of substituted aza-triangulenium fluorescent dyes having a hydroxy group attached to an aryl as quenching group. The new substituted aza-triangulenium fluorescent dyes may be attached to a linker, conjugated to carrier molecule such as e.g. a protein, a nucleic acid, a lipid, or a saccharide, or deposited or immobilized on solid support materials. The substituted aza-triangulenium fluorescent dyes are useful for various purposes, including use in sensors for monitoring or determining the concentration of analytes, such as H+(pH), Na+, K+, Ca2+, O2, CO2, H2O2, ionic strength, redox potentials, metal ions, and metabolites.

Abstract: The present invention relates to a method for the production of a sol-gel based matrix. The method comprises the steps of: a) providing a first alkoxysilane of the general formula: R1—Si(OR2)3 and a second alkoxysilane of the general formula (I): b) preparing a first sol-gel component by polymerization of the first alkoxysilane in the presence of an acid catalyst, c) preparing a second sol-gel component by polymerization of the second alkoxysilane in the presence of an Lewis acid catalyst, d) Mixing the first sol-gel component and the second sol-gel component for the preparation of a sol-gel based matrix. The above method results in a sol-gel based matrix with high stability and high porosity. The sol-gel based material may be used for the production of a composite or sensor suitable for monitoring analytes. Methods for preparing these composites or sensors are provided as well.

Abstract: A tank ventilation device for a motor vehicle includes a ventilation line, connected on one side to an accumulator for gaseous hydrocarbons and connected on another side via a connection to a filling tube for filling a tank of the motor vehicle, wherein the ventilation line is connected to the tank so that gaseous hydrocarbons which are displaced during refueling are re-circulated toward the connection via the ventilation line, a device for applying a pressure on the ventilation line for carrying out a leakage test of the tank ventilation device, when the filling tube is closed with a closure device, and a float body provided in a region of the connection of the ventilation line to the filing tube for preventing entering of liquid fuel into the ventilation line.

Abstract: To avoid damaging the electrical braking system of a motor vehicle due to driving with an applied parking brake, the parking brake is automatically released, if the speed of the motor vehicle exceeds a prescribed minimum value, and the drive unit of the motor vehicle is driven in a specific operating state, and at least one operating element (e.g. gas pedal, gear shift lever, clutch pedal, safety belt, etc.) of the motor vehicle has been actuated by the driver of the motor vehicle. Sensor signals of sensors that sense the state of the above parameters are subjected to a plausibility check.

Abstract: Proposed is a simple and cost-effective method that enables a safe operation of a motor vehicle comprising an electrical braking system with a parking brake. During the parking of the motor vehicle, measuring processes are carried out in a certain time interval spacing, in which measured values of at least one vehicle-specific characteristic parameter are determined. In connection with the measured values determined in the measuring processes, a current desired value for prescribing the brake force for the parking brake is determined.

Abstract: A system and method for allowing gaming device participants to effect trades of payout and other participant credit accumulation for gaming bonus events. A player engages in play of a gaming activity, such as a slot game, which includes a standard mode of play and a bonus mode of play. A trade is proposed of player assets for at least one bonus event. A trade amount is surrendered by the player as part of the trade for the bonus event, and the bonus event is presented to the player for participation, thereby allowing the player to engage in bonus activity otherwise unavailable to the player.

Abstract: In a method for controlling the braking process of a motor vehicle, nonlinear boosting of the braking force is performed if the actuating speed of the brake pedal exceeds a specified trigger threshold value. This trigger threshold value is formed as a function of the instantaneous speed of the motor vehicle, the pedal position of the brake pedal or a variable directly proportional thereto, and of a motor vehicle specific, brake dependent correction value.
